Sage Days 73 in Oaxaca, Mexico May 04-07 2016

Sage is an open source software for mathematics. This is the webpage for the Sage workshop prior to the conference Flat Surfaces and Dynamics of Moduli Space to be held in Oaxaca May 08-13. The aim is to:

  • introduce Sage to people from Oaxaca or assisting to the conference
  • have program and code presentations about geometry and dynamics of surfaces
  • help people to implement their own projects

It is intended to be a small workshop (10 to 15 people) focusing on coding sprints.

Projects

  • Computing Teichmueller maps between translation surfaces (Maxime)
  • merge the two flatsurf projects https://github.com/videlec/sage-flatsurf and http://www.labri.fr/perso/vdelecro/flatsurf.html (Pat, Vincent)

  • visualize the translation structure induced by a differential (Anja)
  • Subgroups of SL(2,R) given from generators. Design an algorithm that given a finite set of matrices in SL(2,R) answers whether the group generated by these is
    1. not discrete
    2. has finite covolume
    3. has infinite covolume
    In case 2. and 3. the algorithm should also output a fundamental domain and generators in canonical forms. (Charles, Vincent)
  • Affine interval exchange transformations (Charles)
  • ... add your own project ...
